The car sound diffrent all together it runs ruffer sounds worse ect but I can drive it do like 10 min and it's okay and then just instantly just horrible.. Any ideas ware to start

get some maf cleaner and throttle body cleaner and clean all the intake pieces and sensors. run some injector cleaner through it. make sure your plugs, wires, and cap, rotor button are in good shape. and clean out the egr.
